Abstract

A falling weight impact testing machine includes a base, a sliding rod group, an impact group, a pulling group, a clamp group and a control unit. The control unit drives the suspension of the pulling group to the clamping position and is located above the impact group, and the control unit drives the pulling group to complete its engagement with the impact group. The control unit is then operated to displace the pull group together with the impact group along the slide bar toward the upper post until the release position is near the upper post. This allows the subsequent drop weight test procedure to be performed. According to the method of constructing the object to be measured from the top and the weight of the drop, the impact test was carried out.
